CRUDE-OIL BURNER.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed December 13, 1909. Serial No. 532,794.

To all whom it may concern:

Be it known that we, l/VILLIAM L. LUB

BOOK, residing at Houston, in the county of Harris and State of Texas,and SAMUEL HAMBLEN, residing at Poi-tales, in the county of Rooseveltand Territory of New Mexico, have invented certain new and usefulImprovements in Crude-Oil Burners, of which the following is aspecification.

Our invention is in the nature of an improved portable crude oil burner,more particularly adapted for burning crude oil; and it primarily hasfor its purpose to provide a burner of this character, of a very simpleand inexpensive nature, easily manipulated, and absolutely safe in itsoperation.

In its generic nature, our invention embodies a novel construction ofburner, applicable to any ordinary cooking or heating stove orfire-place, and it includes a novel cooperative arrangement of parts,whereby, in its operation, it will burn the gas or vapor from the oilonly, and does not consume the oil until it is transformed into vapor.

In its more subordinate features our invention consists in certain novelarrangement and peculiar combination of parts, all of which will behereinafter fully described and specifically pointed out in the appendedclaims, reference being had to the accompanying drawings, in which-'Figure 1, is a view illustrating our improved burner as in use on anordinary cooking stove. Fig. 2, is a vertical section thereof. Fig. 3,is a detail perspective view of the base portion of the burner. Fig. 4,is a similar view of the burner end. Fig. 5, is a detail view of the cupor batlle member, hereinafter specifically referred to. Fig. 6, is aperspective view of a modified form of our improved burner. Fig. 7 is avertical section of the form shown in F i 6. Figs. 8 and 9, are diagramshereinafter specifically referred to.

Referring now to the accompanying drawings in which like numerals andletters designate like arts in all of the figures, 1 denotes a castlIOIl cylindrical base having a vertical flange 1 and a hub portion 1,having a central aperture 1. The hub portion 1 has its upper end formedwith a circular horizontal enlargement 1 the upper face of which isconvexed, as shown by 1", the reason for which will hereinafter beexplained. The body 1 is also provided with a suitable number ofintegral legs 1", for conveniently restin the burner on the stove orfire-place, an also to provide a suflicient space below the body 1 for0011- veniently attaching the feed pipe 2, which is provided with aregulating valve 2, as clearly shown in Fig. 1; and the said pipe 2, inpractice, is joined with any suitable source of supply.

A supplemental feed pipe section 3 joins with the pipe 2 and the saidpipe 3 is of a diameter to pass freely up through the bore of the hubl", of the base, and in practice, the upper end of the said pipe 3 isprojected above the convexed surface of the hub of the member 1, and thesaid projecting portion is formed with an external thread 3, as shown.

t designates a cast iron body having an internally threaded socket 1 toengage the threaded end of the pipe 3, and the lower face of the saidmember 4 is concaved as at 4 to snugly seat against the convexed face ofthe hub member 1. The body 4 is also provided with a jet opening 49 thatcommunicates with the socket 4i and the pipe 3, and discharges into abowl surface 4: on its upper end, which upper end is in the nature of avertical extension rim 4; having a downwardly beveled surface 4., asshown in Fig. 2.

(3 designates a cap or ballle member having an inverted cup shape, andof a diameter slightly in excess of the extension 4L, of the member 4,whereby an annular jet or cscape channel 5 is provided between themembers 6 and 4, and the bottom of the annular portion or rim (3 isbeveled on a plane with the beveled surface 1 of the member to rest onsaid surface. The cap member 6 has a suitable handle portion 6".

From the foregoing description taken in connection with the accompanyingdrawings the ad vantages of our invention will be apparent to thoseskilled in the art to which it appertains.

The oil as it comes up through the feed pipe 3 discharges through thejet aperture 4 of the member 4, into the bowl end 1 thereof, which formsan oil receiving cup. As soon as the member 4 and the member 6 areproperly heated, the oil, as it passes into the space under the cap (5,boils and generates gas and escapes through the jet orifices 6 or as thecase may be, where it mixes with air and burns with a blue flame. Shouldthe oil in the cup 1 overflow and run out through the openings 6 (m theforms shown in Figs. 1, 2 and 3 of the drawings), the drippings willfall on the surface 1 of the base, which being hot will cause thedrippings to splatter and become ignited, thus the overflow or drippingsof the oil will be consumed before they reach the bottom 1 of theburner. In the forms shown in Figs. 6 and 7, however, the drippings fromthe apertures 6O" will fall directly into the base member 1 In Figs. 6and 7 is illustrated a modlfied form of our improved type of burnerwhich embodies the same generic features as shown in Figs. 1 and 3. Inthis form the rim or disk 40 is of considerably larger diameter than thedisk 4 shown in Fig. 2, and it is made convexed and formed with a seriesof ridges 40 that act as rii'fles or retarding means to keep the oilthat drips over from the bowl 4 from flowing quickly toward the outeredge or rim of the disk 10 By having the disk 40 large and ridged, asshown in Figs. 6 and 7, the oil is retained longer on the disk, and agreater quantity can constantly be vaporized than is possible in theform shown in Figs. 1 and 2, and the cap plate in the modified form,designated by 60, is made dome shaped with lts base of a diametersubstantially that of the disk 40 and provided with jet outlets 60 asshown. The increased size of the cap 60 also providing a large heatingsurface for facilitating the vaporization of the oil. In the form shownin Figs. 6 and 7, the circular en largement 1 shown in Figs. 1 and 2 isnot required.

In the practical construction our improved burner may be constructed, asshown in Figs. 1 to 6, rectangular or elongated, as diagrammaticallyrepresented in Figs. 8 and 9, or any other desired shape, and of anymaterial adapted for the purpose, the exact shape depending largely uponthe practical purpose for which it may be used, as the same can bereadily applied to any cooking or heating stove, fireplace, green housesor hot house, with or without legs, as described.

What We claim is:

1. A crude oil burner comprising a base having a vertical annular flangeand a centrally apertured hub portion, said hub portion having acircular horizontal enlargement, said enlargement being convex on itsupper face, a member having an aperture therethrough, and an internallythreaded socket in its lower end, said member being adapted to seat uponthe convex face of the enlargement of the hub portion, and a cap adaptedto seat upon the upper portion of the said member, substantially asshown and described.

outwardly and downwardly inclined face of the hub enlargement being of agreater diameter than the aforesaid chamber Whereby the unconsumeddrippin'gs from the said chamber will be received thereon, for thepurposes described.

3. In a crude oil burner, a base having an annular vertical flange, anda centrally apertured hub portion, a member having a central apertureadapted to rest upon the upper face of the hub portion, said memberhaving an internally threaded socket in its lower end, a feed pipehaving an externally threaded portion adapted to fit within theinternally threaded socket of the said member, said member also havingits upper end formed with a concaved depression, and a cap memberadapted to seat upon said member over the concaved portion thereof, saidcap member having discharge outlets, substantially as shown.

4. In a crude oil burner, a base having an annular Vertical flange, anda central hub portion, said hub portion being centrally apertured andhaving an enlarged circular portion at its upper end, said enlargedcircular portion being convexed on its upper face, a member concaved onits upper and lower ends and adapted to seat upon the horizontalenlargement of the hub portion and over the aperture therein, saidmember being centrally apertured and having an internally threadedsocket at its lower end, a feed pipe extending through the aperture inthe hub portion, said feed pipe having its end externally threaded andadapted to engage the internally threaded socket of the said member,said member having a circular flange, and a cap member having a chamberdisposed over the upper end of the said member and adapted to rest uponthe flange of the said member, saidcap having discharge outletscommunicating with the chamber, all being arranged substantially asshown and described.
